2 main parts of a syringe
plunger and barrel
considered an open system of blood collection since blood is exposed to the environment and healthcare professionals; prone to contamination
needle and syringe method
closed system of blood collection because blood drawn passes directly into the tube with no exposure to the environment or to healthcare professionals; two-way system
evacuated tube system
evacuated tube system includes:
-multisample needle
-a tube adaptor/holder
-sample tubes
TRUE OR FALSE: The longer the blood collection time, the lower the chance of injury.
FALSE: The longer the blood collection time, the higher the chance of injury.
liquid portions of whole blood
plasma and serum
liquid portion of unclotted blood; has unused fibrinogen
plasma
liquid portion of clotted blood
serum
3 layers of plasma
-plasma

-unclotted rbc
2 layers of serum
-serum
-clotted rbc
Centrifuge separates based on __________.
specific gravity/weight
separates rbc from serum or plasma
thixotropic gel
no additive; plastic needs inversion, glass serves as clot activator (no inversion)
